[issue2986] difflib.SequenceMatcher not matching long sequences

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

This appears to be one of at least three duplicate issues: #1528074, #2986, and #4622. I am closing two, leaving 2986 open, and merging the nearly disjoint nosy lists. (If no longer interested, you can delete yourself from 2986.) #1711800 appears to be slightly different (if not, it could be closed also.)

Whether or not a new feature is ever added (earliest, now, 3.2), it appears that the docs need improvement to at least explain the current behavior. If someone who understands the issue could open a separate doc issue (for 2.6/7/3.1/2) with a suggested addition, that would be great.
